Fitting requirements
Measure the window
Start by carefully measuring the width and height of your window frame. This is important for a perfect fit. Write down the measurements and share them with us when you order.
Prepare the window frame
Use a non-abrasive cleaner to make the frame free of grease and dirt. A clean surface makes sure the seal stays put.
Fit the glazing clips
Use the glazing clips for a firm hold. Attach them to the frame.
Attach the window seal
Place the sheet on the frame and make sure it fits snugly. Check that warm air can’t get in anywhere.
Connect the air conditioner
Push the air hose of your air conditioner through the opening in the acrylic. Make sure it sits airtight. This keeps the cold air in and the warm air out.
